Lock improved structure opened by magnetic induction

The utility model is an improved structure of lock body opened by magnetic induction, the main structure is that: a cohesion seat is pivoted with one end of a U-shaped bending lock lever on the surface of shell, and the other end of the lock lever is pivoted and extends into the concave hole corresponding to the other side of the shell, a card-reading device is arranged in the shell, the card-reading device is jointed with an electromagnetic coil that can drive a movable bolt expanding and contracting, which can change the holding status of a lock bolt, when is locked, the lock bolt is embedded into the lock groove pre-arranged on the extending end of the lock lever using a lock part of one end thereof, the card-reading device is driven by a magnetic induction card, which makes the electromagnetic coil drive the movable bolt shrinkage, relieves the slip restriction to the lock bolt and makes the lock part detach the lock groove, the lock lever is free from locking and can be opened, a better locking and protection efficacy can be achieved by the electronic induction of the magnetic induction card and the card-reading device.
